Enthusiast 3D prints an Aston Martin DB4

New Zealand enthusiast Ivan Sentch is in the process of 3D printing a 1961 Aston Martin DB4. Engadget reports that he bought a $499 Solidoodle 3D printer and has been working on this project since December 2012. Using a Nissan Skyline as a donor car, he'll make a fiberglass mold of the print and hopefully transform this thing into a drivable, street-legal car for a fraction of the cost of an authentic DB4.

Audi A2 EV won’t make production – but you knew that

Audi has revealed that it’s dropped plans to put the A2 electric concept – first revealed at Frankfurt 2011 - in to production. Back in June 2012 we reported that the Audi A2 EV wouldn’t make production as Audi had decided that the market simply wasn’t there for a £40k electric city runaround. Now that appears to have been confirmed by Audi in conversation with Autocar.

Ownership costs of traditional versus alternative fuel vehicles

As gas prices remain high, and an increasing number of automakers roll out plug-in hybrid cars and full-electric vehicles, it's becoming easier to be tantalized with the idea of driving right past the gas station and simply "plugging in." The debate ensues when it comes to cost: These alternative fuel vehicles mean a larger outlay of cash at the onset, but the long-term fuel savings could make the purchase worthwhile. To help straighten out this numbers game, we use the Department of Energy's Vehicle Cost Calculator to compare alternative fuel vehicles with their gasoline-only counterparts. For each scenario, we assumed that our hypothetical owner was able to get the full $7,500 federal tax credit and a $2,500 state tax credit, such as is available in California.
